I come and I go, more than once in a day.
Yet I've always been here; for eons my stay.
A bearer of life, I bring fear and great dread;
A destroyer of old, millions by me are fed.
Artists and poets my presence inspires,
My moods, they are varied, my journey ne'er tires.
Once I was greater, but my time comes again.
Can you yet name me, my riddling friend?

Answer

The Sea is my name, or Ocean some say,
My tides wax and wane twice each short-lived day.
Many a life my waters have seized,
But I give back aplenty with food for your need.
My reach was broader many years ago;
Melting ice ensures that again I will grow.
If you have enjoyed this riddling task,
Rate this puzzle highly, I fervently ask.Hide

First of all, as one poet to another I praise you for a verse well written. As for the teaser I liked it also although I thought more along the line of life and death. Your answer was very good. Thank you for a job well done.
